Answer:
When animal cells are put in fresh water, water diffuses/moves into the cell, if too much water moves in the cell will burst. If you put a freshwater fish in salt water its cells would lose water and shrivel because the water has more salt than its cells.

What do you think makes a skin cell different from a hair cell?
Answer:
Hair grows by forming new cells at the base of the root. These cells multiply to form a rod of tissue in the skin. The rods of cells move upward through the skin as new cells form beneath them. As they move up, they're cut off from their supply of nourishment and start to form a hard protein called keratin.
Explanation:
Skin cells are designed to be shed and replaced quickly, and they lack mitochondria (which helps to generate energy).
What is a cell?Cells are the foundational building blocks of all life. Many of cells make up the human body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Hair grew back by establishing new cells at the root's base. These cells divide and multiply to form a tissue rod in the skin.
As new cells form beneath them in that case, the cell rods starts moving upward through the skin. As they progress, they are cut off from their food supply and begin to form keratin, a hard protein.
Thus, this way, it can be concluded that, hair cells are different from skin cells.

It's actually D on edge2020. Tundra has limited veg, the two types are alpine and artic, and temperatures can get below -20F. Tundra can support animal life, but it's just extremely harsh and unforgiving.
The statement that is not true about the tundra is the tundra biome doesn't support animal life. So, the correct option is D.
What is Tundra?Tundra biome is found at high latitudes, where sunlight is low. The soil in this region is completely frozen and nutrients are limiting. The average temperature of this region is below -10°F. The vegetation consists of low shrubs and grasses.
As the nutrients are limited in the tundra biome, it has limited vegetation. There are two main categories of the tundra biome i.e. Arctic tundra and Alpine tundra. Animals such as the arctic hare, the arctic fox, the musk ox, the polar bear, etc. are present in the tundra habitat.
Therefore, the statement that is not true about the tundra is the tundra biome doesn't support animal life.

In the United States, alcoholic beverages that are sold in stores display a government warning stating that pregnant women should not drink alcoholic beverages. This is because it prevents cleavage division from occurring, so a zygote cannot become a blastocyst. if a woman drinks alcohol while she is pregnant, she may not be able to ovulate again after childbirth. studies have proven that alcohol consumption causes long-lasting disorders in the fetus. the science of chemistry has shown that alcohol is a reactive substance that may interfere with the mother’s food digestion.
Answer:
The correct answer is - studies have proven that alcohol consumption causes long-lasting disorders in the fetus.
Explanation:
Alcohol can cross the barrier that the placenta creates between the mother and fetus so the alcohol can negatively impact the fetus or newborn by various means.
It can harm the fetus as it may result in damage to the cells of the fetus. Brain cells and spinal cord cells are prone to such kind of alcohol toxicity or syndrome. Alcohol spectrum disorder that affects the development of the baby which could be long-lasting.

Answer:

If Guanine makes up 24% of a DNA sample is the percentage of Adenine?
A. 24%
B. 48%
C. 26%
D. 52%
Answer:
20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.
Explanation:
sorry if that didnt help but i certainly hope that it did!!!

Answer:
Paramecium and amoeba live in fresh water. Their cytoplasm contains a greater concentration of solutes than their surroundings and so they absorb water by osmosis. The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane.

Why is the cell membrane considered selectively permeable? Because some materials can come in and some materials must stay out Because some materials can come in and some materials must stay out Because it forms a barrier where all materials can get through Because it forms a barrier where all materials can get through Because it forms a barrier where no materials can get through Because it forms a barrier where no materials can get through
Answer:
Because some materials can come in and some materials must stay out
Explanation:
Cell membrane is a structure that covers or bounds the cytoplasmic layer of every living cell. It is made up of mostly lipids. According to this question, it is regarded as selectively permeable. This means that it selects what goes into the cell and what comes out.
The cell membrane is capable of this because of its amphipathic nature i.e contains both hydrophilic and hydrophobic regions. Because the cell membrane controls what goes into the cell and what comes out of the cell, it is referred to as selectively permeable as some materials can come in and some materials must stay out.
